TRAIN-LINE nncnrracm.

. Application led October 6, 1919. Serial No. 328,811'.

To all whom it may concern.'

Be it known that we, LYNN G. RILEY, a citizen of the United States, and a resident of Wilkinsburg, in the county of Allegheny and Statel of Pennsylvania, and HARRY R. MEYER, a citizen of the United States, and a resident of Wilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful 1o Improvement in` Train-Line Receptacles, of

which the followin is a specification.

Our invention re ates to connecting dev vices for multiple unit control circuits on electric railway cars and particularly to i5 train line receptacles for such control circuits.

One object of our invention is to provide means for rmitting the insertion of the train line jumperl in the receptacle only 2o in such position as will insure the proper connection of the control circuits from car tocar.y

Another object of our invention is to provide simple and 'easily operable locking means for retaining the train line jumper in its o erative position in the train line receptac e, which is mounted under the platform of the car.

Another object of our'invention is to provide means for holding said locking means in its locked position, thereby precludiiig accidental movement of the locking means and possible interruption of the control circuits. 4

In practicing our invention, we provide the usual receiving receptacle with a peripherally adjustable locking ring, which is, in turn," provided with' two longitudinal slots in its inner periphery. Another longitudinally extending slot is provided in the outer periphery of the locking ring,"to co-opei'ate with a depending lug on one of the hinge members of the cover of the receptacle to retain the locking ring in its locking position. The jumper head casting is provided with lugs or bosses cui-operating with the slots in the inner periphery of the.

locking to rmit the insertion of the jumper h o. y when the locking ring is in a predetermined position.

In the two sheets of drawings, Figure. 1-

is a vertical sectional view of the device embodying our invention as used in connection with the receiving receptacle, with a jumper head inserted in its operative position; Fig. .2 is a sectional view on the line II--II of Fig. 1; Fig. 3 is a front view of the locking ring; Fig. 4; is a top view, partially in section, along the line IV--IV of Fig. 3; Fig. 5 :is a lon itudinal sectional view along the line V of Fig. 3; Fig.' 6 is a front view of the receiving receptacle, and'Fig. 7 is a side view, partially in section, of the receptacle.

A receiving receptacle 1, substantially circular in contour is provided, at its rear end,

with a cover mem'ber 2 suitably secured thereto, which cover member serves to protect the train line control wires 3, which are united in the form of a vcable 4 and inserted in a conduit (not shown) under,

:which is, in turn, provided with a number of circular openings 10 to permit the receptacle to'be secured to a part of the car platform. Two lugs 11 are provided to permit' the mounting of the receptacle underneath the floor of the car platform if desired. Each of the lugs 11 has a projecting boss 12 that is rovided with a circular opening 13 to receive ahin'ge pin 14, upon which pin is operatively mounted a flat cover member 15 having two hinge lugs 16 and 17. The lug 17 is substantially concentric with the hin pin 14, but the lug 16 is of substantial y cam shape eccentric to the hinge pin 14 as shown in Fig. 1. A coiled spring 15a is provided to bias the cover member 15 to its closed position. A plurality of radial bolts 18 are' provided in the receptacle 1 for pu hereinafter specified.

A circular loc g ring 19, havin a radially rejecting arm 20, is provi ed with two ongitudinal slots 21 and 22 im its inner surface, the `slot 22 meeting and cooperating with a peripheral slot 23. A

longitudinal slot 24 is provided in the outer` periphery of the locking r' 19. the slots 21, 22, 2a and 24 having a eenige span relation to each other. An end ring 25 is suitably secured to one end of the ring 19,

and co-operates with machined parts thereof to form an annular groove 26. A plurality of radial pins 27 are located in the groove 26, being suitably secured to the ring 19. When the locking ring 19 is placed in its operative position in the receptacle l, the inner ends of the bolts 18 project into the groove 26 and prevent longitudinal movement of the ring relatively tothe receptacle. The pins 27 co-operate with the bolts 18 to limit the peripheral movement of the locking ring 19.

Fig. l shows one jumper head of a jumper cable, which comprises a hollow casing 28 subst-antially circular in contour and provided With two radial lugs 29 and 30 on the outer surface of the casing. A cable 31 comprising a plurality of individual conductor wires 32 is located in the casing 28, the conductors 32 terminating in suitable contact terminals 33 positioned in an insulating block 34 and co-operating with the contact terminals 6 to complete the control circuits betweeml ytwo .adjacent cars. An opening 35 is provided in the .casing 28 to permit the pouring of insulating material in the space surrounding the end of the wires 32, to insulate them and to prevent the entrance of moisture into the body of the cable 31, the opening 35 being closed by a screw plug (notA shown).

Assuming that the jumper head is not in the receptacle 1 and that it is desired to insert same and'thus connect the control circuits, thelocking ring will then be in such position in the receptacle 1 thatthe lug 20 will be in a vertically downward position, that is, it will be shifted in a clockwise'direction from the position shown in Fig. 3. The cover member 15 will be in a position to close the opening of the receptacle 1, 4and the depending portion of the hinge member 16 will be in the slot 24 and lock the ring 19 in its sition. The cover member 15'may first e raised, thus disengaging the hinge member 16 from the slot 24 and'perimtting the ring 19 to be moved in a counter-clockwise direction until its movement is arrested by the engagement of two of the pins 27 with two of the cooperating bolts 18. v When the rin is in this position, which is that shown in Fig; 3, the slots 21 and 22 will be in the position shown, andthe bottom surface of depending hinge 16 will rest upon the outer ery of the 'upper part of the adjacent toA the slot 24, thus holding the cover member 15 in a substantially horizontal tion.

e jumper head' 28 may then be inserted in the receptacle 1, the lug 29 entering and passingtliroughvthe slot 21, and the lug 30 enterin and passing through the slot 22 and being positioned in the slot 23. The

.peripheng 1%' ring 19 may then be moved in a clockwise direction until the lug 20 is in a vertically depending position and two, of the pins 27 engage two of the co-operating bolts 18. When the locking ring is in this position, the hinge member 16 will again engage the slot 24 and preclude a peripheral movement such as might be caused by the jolting and jarring of the car in o eration.

By the use of the device em odying our invention, we provide a positive means for preventing the insertion of the jumper head except in a predetermined position, which will insure proper connection of the control circuits from one car to the other. The device prevents alsvo the possibilit of the jumper head being j arred out and interrupting the control circuits and makes possiblev the easy and quick insertion and removal of the jumper head. If the ring is not moved to its locked position, the cover member will not close down to the position shown in Fig. 1 and the cover member therefore acts as a tell-tale to show. whether or not the locking ring has been properly positioned and locked.

While we have shown one embodiment ofA our invention,` various modifications may be made therein without departing from the spirit and scope of our invention, and we desire that only such limitations shall be imposed thereon as are imposed 'by the prior art or are specifically set forth in the appended claims. f

e kclaim as our invention:
